Stay active and connected with the regular-sized vívosmart HR Activity Tracker with Wrist-Based Heart Rate Monitor in black from Garmin. This model fits wrists 5.4 to 7.4" around. It tracks the number of steps you've taken, your distance traveled, calories burned, floors climbed, and more, and displays it all on its 1" touchscreen. Additionally, the vívosmart HR uses built-in Elevate technology to measure your heart rate continually. It helps you to quantify your activity intensity level and subsequent calorie-burning better. The vívosmart HR also tracks time slept and functions as an alarm clock. When connected to compatible devices via Bluetooth Smart, vívosmart HR transmits your activity to the free Garmin Connect mobile app while displaying phone call, text, and email notifications on the wristband's touchscreen.
